PREVENTIVE MAINTENANCE SCHEDULE…
WEEKLY
• Check electrolyte levels (see water additions).
• Equalize charge (heavy use application), if not using a GNB
® EHF-series charger.
QUARTERLY
• Equalize charge, if using a GNB ® EHF-series charger.
MONTHLY
• Record electrolyte specific gravities.
• Equalize charge (light use application), if not using a GNB
® EHF-series charger.
• Inspect the cables and charging plugs.
• Clean the top of the cells.
SEMI-ANNUAL
• Inspect the charger. Confirm proper output voltage and current.
Check for external damage, frayed cables, or worn connectors.
• Clean the exterior of the battery.
TROUBLE SIGNS
Battery temperature rises more than 25° F (14° C) during a normal charge.
Open circuit cell voltages vary by 0.15 volts or more and specific gravity varies by
0.020 or more during equalizing.
The top of the battery is always wet or one cell requires excessive water.
9. MAINTENANCE CLEANING
The top of the battery should be kept clean and dry. Keep the vent caps in place during
use and charging. Remove the vent cap only to observe electrolyte levels, make water
additions, take temperatures, or take specific gravity readings with a hydrometer. If the
battery requires cleaning, contact your local GNB Industrial Power servicing
representative. The solution used to clean and neutralize the outside of the batteries
should be disposed of in an environmentally safe manner.
